Castle of Braga is a historical fortification and defensive line encircling the city of Braga. While, in fact, the only remains of this structure are the various gates and towers along its perimeter, the main keep tower, located in the civil parish of São João do Souto, is the only true remnant of the medieval castle.
The oldest walls were built during the Roman age in the 2nd century AD. Although reliable information about the evolution of Braga's early defences are lacking, it is known that, from the 11th century, a second wall was under construction, to the south and to the west. The first documented reference to a walled keep occurred in 1161. Around 1210, the walled compound was likely expanded, since documented references referred to road and gate of Souto. It was in 1300, that King Denis ordered the construction of the castle.
The keep (Torre de Menagem) consist of a rectangular footprint and vertical block covered in tile. The facades are built in granite masonry that is slightly staggered closer to the ground. The design is trimmed with chamfered merlons, battlements with gargoyles and machicolations to the corners. It is four stories, or approximately 30 metres in height, with the first floor considerably taller than the remaining: it is about 12 metres tall. This section is marked by grooves where other buildings abutted the structure, some stones with identifiable inscriptions.
Of the walls of the city, only the gate, tower of Santiago, tower of São Sebastião and Porta Nova remain (the latter being completely remodeled in a Rococo style and completely different stylistically).
The demolition of the grounds began in 1858. After the beginning of the 20th century, many other lines of the castle were destroyed. Few remnants of the medieval lines remain today. The ancient wall can be seen in some of the backyards of homes along the Rua do Anjo and Rua de São Marcos. Still further, there still exists the Gate of São Tiago, even if partially altered due to the construction in the second half of the 18th century, through the addition of the Capela da Senhora da Torre. Along Rua de São Marcos, in 1985, one property owner constructed over the foundations of one part of the wall, while in March 1990, there was a collapse of one part of the ancient wall, during the demolition of the old Facho garment factory.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
